Golden Fuel Systems (Springfield, MO) founder Charlie Anderson displays an example of “good grease” suitable for use in a veggie-oil-powered vehicle.
Marcos Markoulatos and Ty Martin, of Lawrence, Kan., both run their trucks on filtered waste vegetable oil.
Because vegetable oil is less explosive than gasoline or diesel at normal temperatures, carrying an extra jug of oil in your vehicle is not hazardous.
In addition to making engine modifications, you must filter waste vegetable oil prior to burning it in your vehicle.
Running a truck on vegetable oil does not decrease power significantly. This veggie oil powered Ford F250 easily handles a camper trailer.
